LoL! I could not tell the thickness just from the cover. But I get ya. I'm not saying do it all in one go, but even a tripod and camera will do some good work. If you take pics I can help edit and put them all together in a proper document.
I have done a bunch of digitizing old files and the flatbed scanners can do good work but they are slow since it is one page at a time. The feed style scanners are great until it doesnt want to feed properly or jams up. They do make it easy to do a double sided scan of a stack of papers though.
Maybe it is something new creature inductees have to work on....
